Buying Happiness
Spending money is often a part of the search for happiness.
Some people purchase objects, such as cars or watches, to make themselves feel good.
( 1 ), money can also be spent on experiences, such as taking a vacation or eating an expensive meal.
According to research by Ryan Howell of San Francisco State University,
even though more people seek happiness by buying material goods, spending money on experiences tends to make people happier.
In his study, Howell talked to individuals before and after they made spending decisions about both material goods and life experiences.
Before spending, most respondents expressed the belief that an experience might be more enjoyable
but a new possession would be worth more to them.
When they were interviewed again after spending, the respondents' answers generally showed that they ( 2 ).
The majority reported that life experiences had given them more value for their money.
According to Howell, since economic value is usually associated with objects rather than memories,
it is difficult for people to estimate the value of experiences beforehand.
The type of purchase alone does not determine how much happiness it brings, however.
Howell also found that the ( 3 ) is strongly related to how much satisfaction people get from their purchases.
For example, when people decided to buy an experience based on their personal interests and values,
it made them feel better about themselves and more connected to others.
On the other hand, when people were motivated to spend money to gain recognition from other people,
they reported feeling less satisfaction.

Caulerpa Taxifolia
In 1980, Germany's Wilhelma Zoo began breeding a type of seaweed known as Caulerpa taxifolia to create a faster-growing variety of it than is found in nature.
This variety was particularly useful for aquariums, and soon other facilities began to use it as well.
At some point, however, the seaweed ( 4 ).
In 1984, a single square meter of Caulerpa was found growing in the Mediterranean Sea outside an aquarium in Monaco.
It had most likely entered the ecosystem by being washed down a drain as a result of human carelessness.
By the early 1990s, Caulerpa had spread to at least 38 different sites and was covering thousands of hectares of the ocean floor.
It crowded out native seaweed species and threatened organisms that depended on those plants for food and habitat.
Many experts began arguing that Caulerpa ( 5 ).
This was easier said than done, however, because it had already spread to so many different areas.
Also, because it releases toxic chemicals, most marine animals will not eat it, so it cannot be controlled naturally.
So far, California is the only place that has ( 6 ).
When Caulerpa was discovered in California in 2000, the government responded very quickly.
First, they made Caulerpa illegal, even in private fish tanks.
They covered all the Caulerpa in the ocean with black plastic to cut off sunlight and then pumped chemicals into the water to kill it.
Other areas are also considering removing it from their ecosystems using similar methods because the plant is such a significant problem.
